Could it be your indentation? I don’t know if your config is setup the same as it is in this post, but this won’t work.
I tried using mosquitto but faced weird barriers and errors so I decided to go with the embedded broker instead.
As for my indentation, I think it just got messed up during the copy/paste to this thread, as I’m using what was already templated for me in the file.
Are you sure your MQTT broker is working properly? If you used the AIO installer mosquitto is also installed by default and is not too bad to get going. I had a permission problem with my pwfile but got it sorted. Here are my notes for setting it up from a fresh install:
Edit mosquitto config
sudo nano /etc/mosquitto/mosquitto.conf
delete all text in the file and replace with this:
allow_anonymous false password_file /etc/mosquitto/pwfile listener 1883 listener 9001 protocol websockets user mosquitto persistence true persistence_file mosquitto.db persistence_location /var/lib/mosquitto/ pid_file /var/run/mosquitto.pid
Create password file (user pi), this destroys any existing file:
sudo mosquitto_passwd -c /etc/mosquitto/pwfile pi
If you want to add users to existing password file:
sudo mosquitto_passwd /etc/mosquitto/pwfile username
Test mosquitto config for errors:
mosquitto -c /etc/mosquitto/mosquitto.conf
I had an error where I didn’t have permission to access the pwfile. I had to
killall mosquitto then delete the pwfile in samba, then create a new one for this to work. Once you pass the test above, reboot and test that the systemd instance is loading and running properly:
Test mosquitto systemctl process for errors
sudo systemctl status mosquitto.service
Test mosquitto- subscribe & publish: open two terminal windows and issue these commands in different windows:
mosquitto_sub -d -u pi -P raspberry -t dev/test
mosquitto_pub -d -u pi -P raspberry -t dev/test -m "Hello world"
To view all messages coming through the broker, subscribe to all messages:
mosquitto_sub -u pi -P raspberry -v -t '#'
To see even more details, stop the systemd instance and run just a verbose instance (note, this will not load the preference file)
I just remembered I had this exact same issue when I migrated from a Pi1 to a Pi3. I forgot to update the MAC address in the ST IDE MQTT-Bridge device config options. After I made the changes, it still wasn’t working. I had to delete the SmartApp instance and then setup a new one. Maybe that’s your problem.
I was thinking that as well.
Here are the steps I took on my last build. Hopefully they’re useful to someone.
Build Image from latest raspian and update it
sudo apt-get update; sudo apt-get upgrade
Install All In One homeassistant installer
wget -Nnv https://raw.githubusercontent.com/home-assistant/fabric-home-assistant/master/hass_rpi_installer.sh && chown pi:pi hass_rpi_installer.sh && bash hass_rpi_installer.sh
Reset mosquitto password before we get started. For this example, use username pi and password mqttpass.
sudo mosquitto_passwd /etc/mosquitto/pwfile pi
sudo systemctl restart mosquitto.service
Setup smarthings-mqtt-bridge via npm
sudo apt-get install npm
sudo npm install -g smartthings-mqtt-bridge
setup pm2 to run the processes
sudo npm install pm2 -g
create and edit smartthings-mqtt-bridge config
sudo cp /usr/local/lib/node_modules/smartthings-mqtt-bridge/_config.yml ~/config.yml
sudo nano ~/config.yml
mqtt: # Specify your MQTT Broker's hostname or IP address here host: mqtt://localhost # Preface for the topics $PREFACE/$DEVICE_NAME/$PROPERTY preface: smartthings # Suffix for the state topics $PREFACE/$DEVICE_NAME/$PROPERTY/$STATE_SUFFIX # state_suffix: state # Suffix for the command topics $PREFACE/$DEVICE_NAME/$PROPERTY/$COMMAND_SUFFIX # command_suffix: cmd # Other optional settings from https://www.npmjs.com/package/mqtt#mqttclientstreambuilder-options username: pi password: mqttpass # Port number to listen on port: 8080
Configure the SmartThings Device handler, Device, and SmartApp using steps outlined in https://github.com/stjohnjohnson/smartthings-mqtt-bridge1
Device Settings IP: raspberry pi IP MAC: Raspberry pi MAC Port: 8080
Add mqtt to HomeAssistant config configuration.yaml
mqtt: broker: localhost port: 1883 client_id: home-assistant-1 username: pi password: mqttpass
Add switches to their own file, or configuration.yaml
- platform: mqtt name: "MQTT Dining Room Light" state_topic: "smartthings/Dining Room Light/switch" command_topic: "smartthings/Dining Room Light/switch" payload_on: "on" payload_off: "off" retain: true
start the bridge
pm2 restart smartthings-mqtt-bridge
sudo systemctl restart home-assistant.service
That should do it. You may want to sudo reboot
I’ve been following this thread and @AceoStar instructions as above but I’ve hit a brick wall. I’m running Hassbian and all is set up as above, but running ‘pm2 logs smartthings-mqtt-bridge’ results in ‘Error: listen EADDRINUSE :::1883’. This ‘sudo lsof -i TCP:1883’ results in the following;
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mosquitto 490 mosquitto 3u IPv4 10345 0t0 TCP *:1883 (LISTEN)
mosquitto 490 mosquitto 4u IPv6 10346 0t0 TCP *:1883 (LISTEN)
mosquitto 490 mosquitto 5u IPv6 41596 0t0 TCP localhost:1883->localhost:56404 (ESTABLISHED)
hass 14259 homeassistant 7u IPv6 42713 0t0 TCP localhost:56404->localhost:1883 (ESTABLISHED)
My level of experience on this is fairly limited and if anyone could suggest how I can permanently remedy the problem, I’d appreciate the help. I can kill some or all of the PIDs but the problem returns upon reboot. If I had hair, it’d be torn out by now.
Funnily enough, when I said “all is set up as above” I was entirely wrong and had the wrong port in the config.yml
Thanks for all who contributed here. Much appreciated.
That’ll get ya every time! Glad its working out
Hey this actually came at the perfect time because I have been meaning to do this for the longest time but have not been able to until now! I am following what @AceoStar has posted above and I am coming across a couple of problems though, so maybe you guys could help me with that.
When I try to run “pm2 logs smartthings-mqtt-bridge” I get an error saying that smartthings-mqtt-bridge was not found. I try running “sudo npm install -g smartthings-mqtt-bridge” again and I am also able to edit and view the config file that is made from it. Any ideas on what was wrong? Also, how can I ensure that mosquitto is running properly? I am a complete newbie, so any and all ideas and steps are much appreciated
@AceoStar: This is a great tutorial. I want to add my small contribution, as it isn’t something I’ve seen written anywhere.
Make PM2 start the MQTT-bridge on boot
(only tested on the Pi AIO installer)
First make sure the bridge is running in PM2:
pm2 start smartthings-mqtt-bridge
Save the process to the dump file:
Set PM2 to start on boot:
pm2 startup -u pi
I received this message:
[PM2] Init System found: systemd [PM2] You have to run this command as root. Execute the following command: sudo env PATH=$PATH:/usr/local/bin pm2 startup systemd -u pi --hp /home/pi
So execute the command:
sudo env PATH=$PATH:/usr/local/bin pm2 startup systemd -u pi --hp /home/pi
I hope this works for you guys, let me know if there’s a better way!
@hoffsta Thanks for your post! Would that help the situation I am in as well? I’m not with my pi to try it at the moment
pm2 logs smartthings-mqtt-bridge are you running
pm2 start smartthings-mqtt-bridge?
First thing I’d do is look in /usr/local/bin and see if pm2 and smartthings-mqtt-bridge are installed there. I had an issue with my version of NodeJS not installing packages to that location. I had to remove and reinstall node and npm from a different method.
As for mosquitto, you can do a quick test. Open two ssh windows, in one, type:
mosquitto_sub -d -u username -P password -t dev/test
In the other type:
mosquitto_pub -d -u username -P password -t dev/test -m "Hello world"
Does “Hello World” pop up in the first window?
Of course this depends on you having created a password file in mosquitto. If you haven’t, omit the -u and -P arguments.
@hoffsta oh wow I never even knew I had to start running smartthings-mqtt-bridge. I was following @AceoStar step for step with everything that he wrote, when I get home with the pi I will try starting it and let you know how it goes.
Also another quick question: since I’m installing everything on my pi, when it says
Specify your MQTT Broker’s hostname or IP address here
do I replace all instances of “localhost” with the IP address of my pi?
You shouldn’t need to if you’re on the same Pi. “localhost” ‘127.0.0.1’ or the actual IP address should all work.
@hoffsta Thank you so much for your help! I got it working! Your post about having it run on reboot actually came in very handy today, so thank you very much. How am I able to add a slider so that I could change the brightness of a lightbulb?
Awesome, glad I could help!
light: platform: mqtt name: "Bedroom Light Switch" state_topic: "smartthings/Bedroom Light Switch/switch" command_topic: "smartthings/Bedroom Light Switch/switch" brightness_state_topic: 'smartthings/Bedroom Light Switch/level' brightness_command_topic: 'smartthings/Bedroom Light Switch/level' brightness_scale: 100 qos: 0 payload_on: "on" payload_off: "off" optimistic: false
You won’t see the brightness slider on the front end unless you click into the card for the light. Look into building custom input sliders if you want to see that instead of the on/off switch. I haven’t worked on any of that yet.
Thank you! It works exactly how I always wanted it to. Thank you very much
I have been trying to setup the bridge. I have followed @AceoStar steps. When I enter
pm2 start smartthings-mqtt-bridge I get
/usr/bin/env: node: No such file or directory would anyone understand why? Or what I am doing wrong?
sudo ln -s “$(which nodejs)” /usr/local/bin/node
